Owing to their unique features such as high surface area, rich electroactive sites, ultrathin thickness, excellent flexibility and mechanical stability and multiple surface functionalities enables outstanding electrochemical response which provides high energy and power density supercapacitors based on them. Also, the Van der Waals gap between layered 2D materials encourages the fast ion transport with shorter ion diffusion path. 2D materials such as MXenes, graphene, TMDs, and 2D metal–organic frame work, TMOs/TMHs materials, have been described with regard to their electrochemical properties for MSCs. We have summarized the recent progress in MSC based on well-developed 2D materials-based electrodes and its potential outcomes with different architectures including interdigitated pattern, stacked MSC and 3D geometries for on-chip electronics. This chapter provides a brief overview of the recent developments in the field of 2D material based all-solid-state microsupercapacitors (MSCs). A brief note on the MSC device configuration and microfabrication methods for the microelectrodes have been discussed. Taking advantage of certain 2D materials such as 2D MXenes, TMDs, TMOs/TMHs that provide good surface chemistry, tunable chemical and physical properties, intercalation, surface modification (functionalization), heterostructures, phase transformations, defect engineering etc. are beneficial for enhancement in pseudocapacitance as it promotes the redox activity.

“…Single-walled carbon nanotube thin films were also prepared by vacuum filtration, which can then act as electrodes in micro-supercapacitors [78]. A flexible, in-plane asymmetric micro-supercapacitor was fabricated with electrochemical-exfoliated functional graphene oxide and chemicalreduced, functional reduced graphene oxide films, made through mask-assisted vacuum filtration, and solid polyvinyl alcohol/sodium sulphate electrolyte [170]. In a very recent study, a new micro-supercapacitor was developed with MXene/carbon nanotubes composite, acting as the electrode, and fabricated using photolithography followed by vacuum filtration.…”

The very fast evolution in wearable electronics drives the need for energy storage micro-devices, which have to be flexible. Micro-supercapacitors are of high interest because of their high power density, long cycle lifetime and fast charge and discharge. Recent developments on micro-supercapacitors focus on improving the energy density, overall electrochemical performance, and mechanical properties. In this review, the different types of micro-supercapacitors and configurations are briefly introduced. Then, the advances in carbon electrode materials are presented, including activated carbon, carbon nanotubes, graphene, onion-like carbon, and carbide-derived carbon. The different types of electrolytes used in studies on micro-supercapacitors are also treated, including aqueous, organic, ionic liquid, solid-state, and quasi-solid-state electrolytes. Furthermore, the latest developments in fabrication techniques for micro-supercapacitors, such as different deposition, coating, etching, and printing technologies, are discussed in this review on carbon electrode-based micro-supercapacitors.

“…With the fast expansion of human civilization, environmental issues and energy crises have been closely related to the future of mankind. Clean energy, especially electrical energy, has motivated many researchers to explore new systems for its storage and utilization, 1–5 such as supercapacitors (SCs), fuel cells, secondary batteries and so on. Among them, SCs, especially micro-supercapacitors (MSCs), are in the spotlight because of their high power density and their ability to provide an instantaneous strong current, which are hard to achieve in batteries.…”
